Reflective display apparatus and front light module thereof

A reflective display apparatus, comprising:

• a light guide plate comprising a light incident surface and an inner light outgoing surface, the light incident surface being adjoined to the inner light outgoing surface;
• a light source configured to emit light into the light incident surface of the light guide plate;
• a reflective display panel comprising a display surface toward the inner light outgoing surface of the light guide plate;
• and
• a light redirection film located between the display surface of the reflective display panel and the inner light outgoing surface of the light guide plate, and the light redirection film configured to redirect a traveling direction of the light from the light guide plate toward the display surface, wherein an acute included angle between the light after redirected and a normal line of the display surface is less than an acute included angle between the light before redirected and the normal line of the display surface, wherein the light redirection film comprises a light transmissive film body and a plurality of light redirection microstructures disposed on the light transmissive film body, wherein at least one of the light redirection microstructures comprises a first surface, and a perpendicular distance from the first surface to the display surface decreases along a direction away from the light source.
